Hmmm, NAD doesn't list a model 2600 amp. Their model 2700 is listed at 150 watts. But what watts; these are is questionalbe since the spec's report "Clipping Power" to be only 42 watts. See www.nadelectronics.com Since the 2700 went out of production in 1995, you might want to put it in the dust bin.
Amp overload,! NAD 2600 & maggies 3.5
I got a pair of magnapan 3.5's two months ago and paired it up with the NAD 2600 power envelope amp (150 watts) and a NAD pre-amp series 20, I cannot put the voloume above 4.5 without the amp overloading. Any suggestions? Having the song crap-out every 10 seconds kind of ruins the mood.
